Definitions

  • This invention relates to the field of mining, in general, and more specifically to a comminution arrangement for a mine site, a comminution methodology, a mine site having such a comminution arrangement and a method of mining comprising such a comminution methodology.
  • Run of Mine For example, in a typical mining environment, such as an iron ore mine, Run of Mine (ROM) is delivered to a primary crusher by haul trucks, conveyors and related material moving equipment. At the ROM pad, mined material or ROM is dumped into a primary crusher where large rock fragments are broken into smaller sizes. Crushing to the proper size usually occurs in stages as rapid size reduction, accomplished by applying large forces, commonly results in the production of excessive fines. For this reason, after primary crushing, the material is typically run through one or more secondary crushers. The material is screened after each crushing cycle to separate properly sized particles ("throughs") from those needing additional crushing ("overs"). Additional washing, screening, or other processing may be required to remove undesirable material. The crushed material is then stockpiled awaiting shipment.
  • ROM Run of Mine
  • any delays at the primary crusher generally delays the entire processing of mined ore, which delays mine production and has significant adverse financial effects.
  • delays include oversized rocks delivered to the primary crusher, foreign material entering the crusher (such as ground engaging tools or GET that combine with ore during the mining process), continuity of delivering mined material to the crusher, and the like.
